This is perfect timing! I was debating CMH or LED and went LED as I sourced a screaming deal on one, but something from my old school reef exp keeps tugging me to try the CMH.

I feel like my tent runs pretty cool BUT my light (Meihzi 139w) is less than half of your true wattage, and i was contemplating either a second light to bring it to 300 or switching to CMH.

I cant offer much advice but I can compare as I think if I had another light (now pushing around 300watts) I would want to exhaust heat directly from the tops of the fixtures with some 4" and powerful pc fans or a dc inline for sounds sake. That or maybe splice the led driver and add a couple feet to put them out if the tent. I know my drivers tended to nearly match my leds in heat for my old reef tank.

Any differences so far in leaf texture or growth?

Don't know how to highlight your text, but this is a great idea ! Yes this could work for me too, but if I cut into the "finished" product of the LED lamp I currently have, I won't be able to sell it... or maybe I can.

I have no doubt that removing generated heat before it even enters the tent is.... almost mandatory. I like the idea of separating the driver from the light.

As for the plants and texture well I have no data at all. It does "seem" that the plants like the CMh, but truth be told I have no long term evidence to support or refute my own opinion.

Just a note.... My personal goal is to create and environment the closely resembles the native/natural environment of the Super Hot Peppers.... 80's (degF) with Relative Humidity to match.. 80's %RH. So the more easily I can keep the heat down in the tent the better. I have to keep the humidity high so direct venting is not working out very well.

Good luck with your new LED... keep me posted. Like o know how it works out for you.
